4 Claims.

The present invention relates to shoe machines and more particularly toa machine forperforming a combined ink-marking and perforatingoperation.

For purposes of disclosure the various features of the present inventionare illustrated and described as embodied in the model R machinemanufactured by Western Supplies Company, under my prior patents, Nos.1,834,919 and 1,938,678,

10 which machine has a wide use in the manufacture of shoes to performmany different operations.

Heretofore Western Supplies Company performed the combined ink-markingand perforating operation upon the well-known Western cutl51 outmachine.

The principal objects of the present invention are to produce a simple,inexpensive and efficient combined ink-marking and perforating machine,particularly in the form of an attachment to the 20 model R. machine, tosimplify and improve the inking means by which the marking dieisprovided with ink, and to simplify andimprove the die holder,particularly, with respecttothe rev taining of the chips cut out of thework by the die and the discharge of the retained chips, and withrespect to the securing of the die holder for ready removal in themachine.

To the accomplishment of these objects, and such others as may appearhereinafter, the various features of the present invention reside incertain devices, combinations and arrangements of parts hereinafterdescribed and then: set forth broadly and in detail in the appendedclaims which possess advantages readily apparent to those skilled in theart.

The various features of the present invention will be readily understoodfrom an inspectionof the accompanying drawings illustrating the bestform of the invention at present known to the inventor, in which Figure1 is a view in front elevation of the combined ink-marking andperforating machine;

Fig. 2 is a view in right side elevation;

Fig. 3 is a detail view in perspective showing 45 particularly how thework is gauged when paper is used on the metallic cutting bed;

Fig. 4 is a detail view partly in section in underside plan of the die,the die holder plate, the plunger plate and the means for securing these50 plates together;

Fig. 5 is a detail view in sectional elevation on the line 5--5, Fig. 4;

Fig. 6 is a detail view in sectional elevation on the line 66, Fig. 4;

5 Fig. 7 is a detail view in plan of a modified Fig. 9 is a detail viewin left-side sectional elevation showing the stop for limiting thedownward movement of the die under the influence of the left-handtreadle.

In the embodiment of the invention illustrated in the drawings, theframe of the machine is shown as including a base 9 (Fig. 1), which isrigidly secured to a permanent horizontal support l9 mounted on legs ll.Integrally formed with the base is an irregularly shaped boss [2constituting the work supporting bed. An overhanging arm is integrallycast with the base 9 and includes the standard l3 (Fig. 2), and theoverhanging head H. In the upper parts of the standard and head is anelongated journal for the drive shaft IS. The shaft I5 is operativelyconnected for intermittent rotation with the pulley I5 which is drivenconstantly from some suitable source of power.

Between the pulley l6 and the shaft I5 is a clutch mechanism I!controlled from a foot treadle l8 through a link l9. The clutchconstruction is generally similar to that employed in themachinedisclosed in my prior Patent No. 1,807,952, dated June 2, 1931,which is referred to and described in my prior Patent No. 1,834,919, atpage 2, lines 32 et seq. Since the construction and operation may bereadily understood by reference to my prior patents, it is unnecessaryto repeat the description of the construction and mode of operation ofthe clutch mechanism except to direct attention to the fact that theshaft I5 is operated intermittently.

The shaft l5 carries at its front end an eccentric 29 (Fig. 1), whichrotates within a strap 2| having a downwardly extending arm 22. The arm22 extends between a pair of spaced arms 23 (Fig. 2), forming upwardextensions of a sliding plunger 24. A pin 25 provides a pivot connectionbetween the arm 22 and the arms 23. The plunger 24 is mounted in aguideway formed on the front face of the head l4. A plate 26 having arectangular cut-out portion is attached to the walls of the guideway byscrews 21. A die carrier in the form of a rectangular sliding block 28is mounted in the lower part of the guideway in axial alignment with theplunger 24.

The connection between the plunger and the die carrier is generally thesame in construction and mode of operation as the connection shown in myprior Patent No. 1,938,678, so that it is unnecessary to repeat thatdescription.

The die carrier 28 is provided with a lateral pin 29, (Fig. 9),whichslides in a curved slot 39 'formed in the left-hand side of thehead 24,

This pin 29 is embraced by the When the forward end of the lever 30 ismoved downwardly by the link 32, the die carrier is moved downwardly inopposition to the spring 34, (Fig. 9), which downward movement islimited by a stop pin 35, (Fig. 9), on the standard l3.

As explained in my prior Patent No. 1,834,919, the preliminary downwardmovement of the die carrier provides a safety mechanism preventingaccident to the operatives fingers. Heretofore the cutting edge of thedie was moved, during the preliminary downward movement, into engagementwith the work prior to the throwing in of the clutch to drive the edgeof the die through the work. In the illustrated embodiment of thepresent invention the downward movement of the die carrier 28'is limitedby the stop pin 35 to space the cutting edge of the die slightly abovethe work, the space, however, being too small to receive any portion ofthe operatives finger.

The bottom face of the die carrier 28'is flat, (Fig. 5), to receiveflatwise one face of a plate 36 provided with a pair of mutilated pins3! which enter vertical sockets 38 formed in the die carrier 28. Theplate 36 is secured to the die carrier 28 by frusto-conical surfaces 39,(Figs. 4 and 5), which engage the mutilated portions of the pins 31,respectively. The surfaces 39 are formed on elongated pins 40 mounted toslide in horizontal openings 4| formed in the die carrier 28. Eachsurface 39 is held in engagement with the mutilated portion of one ofthe pins 37 by a spring 42 coiled about a reduced portion of the pin 45and interposed between the pin 45 and a web 43 of the die carrier 28, ascrew 44 carried by the end of the pin 45 acting by engagement with theweb 43 as a stop for limiting the movement of the pin under theinfluence of the spring. Both pins 40 are connected to a common handle45 for operating them to release the pins 31, there being a stop 46 onthe die carrier 28 for limiting the inward movement of the handle." Thepins 45, adjacent the surfaces 39, are provided with a cylindricalportion 4'! of reduced diameter to permit the pins 37 to be readilywithdrawn from the sockets 38 when the handle 45 is pushed inwardly.

'The plate 36 is riveted to the reduced upper ends of four posts 43 thelower reduced ends of which pass through a die block 49, a die restplate 55), and a die holding plate 5!, the lower ends of the posts 48being riveted to the plate 5|. The dies held by the plate 5! comprise acut-out die 52 and a plurality of perforating tubes 53. The ink-markingdie is provided with two continuous marking edges 54 and 55 formed upona stripper plate 55 which is supported upon the lower ends of four posts51 loosely mounted in the plates 50 and 5!. Each of the posts 51 is heldfrom dropping out by a sleeve 58 to which the post is pinned, the sleeve58 being mounted in a recess 59, formed in the block 49. The sleeve 58is held normally in engagement with the plate 50 by a spring 66 coiledabout the post 5! and interposed between the stripper plate 50 and thebottom of a recess 5| formed in the plate 50.

The space between the plate 36 and the block 49 is enclosed by arectangular sheet metal wall 62 the bottom of which is secured to thefour edges of the block 49 and the top of which is secured to the twonarrow edges of the plate 36. The wall 62 forms a chamber 63 forretaining the chips or pills formed by the cut-out die 52 and theperforating tabs which work up from the dies into the chamber 63 throughinlet passages 64 and 65, respectively. If the stripper plate post 51were mounted in the usual manner chips or pills in the chamber 63 wouldprevent the stripper plate 56 from returning to its original positionafter each ink-marking and perforating operation. By securing the posts51 to the sleeves 58 and by mounting the sleeves 58 in the counterboredrecesses 59 all dangers of the chips or pills interfering with theproper operation of the stripper plate is obviated.

The plate 36 is provided with an outlet 66 which is normally closed bythe bottom of the die carrier 28. To clear the chamber 63 of chips thehandle 46 is pressed inwardly to release the pins 31 thus permitting theplate 35 and the die structure assembled therewith to be withdrawn fromthe die carrier 28. After the plate 36 has been separated from thebottom of. the die carrier 28, the die structure may be turned into anupside down position whereupon the chips or pills in the chamber 55 maybe shaken out through the outlet 66.

In some cases, it may be desirable to support the work upon a fiat plate61, (Fig. 7) constituting the cutting bed, supported removably upon theflat upper surface of the work supporting bed l2. To this end the bed I2is provided with four upstanding pins 68 which are received by fouropenings 69 formed in the plate 61. The work may be gauged by anabutment gauge plate removably mounted upon the plate 51. To this endthe plate H! is provided with two holes H which receive pins 12projecting from the bed l2 through suitable openings formed in the worksupporting plate 61.

In other'cases it may be desirable to support the work upon a sheet ofpaper 13 which is fed over the work supporting plate 61 between thepins' 68. When the paper is employed as the normal cutting bed a gaugeplate 14, (Fig. 3), is used. This plate 14 is provided with openingswhich receive pins 15 projecting upwardly from the upper surface of theplate 6'! outside the path of the paper 13. a In the illustratedembodiment of the invention the gauges 6'! and M are shaped to engagethe throat ll of ,a vamp 18, but it will be understood that these gaugesmay be shaped to engage selected edges of any shoe upper part upon whichit is desired to'perform the combined ink-marking and perforatingoperation.

As usual in this class of machines in which paper is employed as thenormal cutting bed, the paper is mounted in a roll 19, is conducted overthe surface of the abnormal cutting bed 67 and is rerolled upon a rewindroll 80. The paper is fed a step, either at the beginning or at the endof a cycle, when the clutch mechanism I! is thrown into operation, bythe rolls 8| and 82. The roll 81 is rotated'intermittently by a ratchet83 of the roller type which is driven by the lower end of a lever 84 theupper end of which is provided with a roll 85, which engages a camsurface 86 formed on the clutch hub. The rewind roll 80 is driven by abelt 81 which passes over a pulley 88 On the rewind roll shaft and apulley 89 constituting the hub of either the pulley IE or the fly wheeltherefor. The belt 81 is not tight so that it may constantly slip overthe pulley 89, thus keeping the paper wound tight on the rewind rollnotwithstanding variations in the diameter thereof. 7

The marking edges 54 and 55 are inked by an ink pad 95, (Figs. 3 and'7), which is mounted in a shallow pan S II- The opposite sides of thepan are provided with blocks 92 the lower edges 15 gagement in themanner illustrated in Figs. 3

and 8 by a coiled spring 05 one end of which is secured to the tray 9|and the other end of which is secured to the carriage 94.

The front and rear faces of the carriage 94 are each provided with achannel 96 which receives a rail 97 secured, respectively, to the frontand rear faces of the work supporting bed I2. The carriage slides on therails 91 to interpose the ink pad 00 between the work mounted on thework support and the combined ink-marking and perforating die.

The carriage 94 is provided with an operating handle 99 by means ofwhich the operative slides the carriage to bring the ink pad 00 beneaththe die and to return the carriage to the position of Fig. 3. In orderto elevate the ink pad vertically into engagement with the marking edges54 and 55, the tray 0! is provided with an angle plate I00 the verticalface of which engages the left-hand wall of the work supporting bed I2,viewing Fig. 3, just as the ink pad 90 is brought beneath the die thusstopping the tray and causing the blocks 93 to slide beneath the blocks92 thereby elevating the ink pad 90 into engagement with the markingedges 54 and 55. When the carriage 94 is returned to the position ofFig. 3 the springs 95 lower the ink pad by sliding the blocks 02 downthe inclined surfaces on the blocks 93.

The carriage 94 may be slid back and forth and the ink pad elevated intoengagement with the marking edges 54 and 55 by a different type ofoperating handle IOI illustrated in Figs. 7 and 8.

The handle IOI comprises two parts, the part I02 being a rigid barprojecting forwardly from the carriage 94 and the part I03 being a leverpivoted to the part I02 and the tray 9|. The bar I02 and the lever I 03are maintained normally separated by a coiled spring I04 one end ofwhich is engaged with the lever I03 and the other end of which isreceived in a recess I05 formed in the bar.

With this construction, the handle IOI may -be grasped to slide thecarriage 94 over the work support to position the ink pad 90 directlybeneath the marking edges 54 and 55 whereupon the bar I02 and the leverI03 may be squeezed to operate the lever I03 and slide the tray 9| tothe left, (Fig. 7). During this sliding movement of the tray 9|, theblocks 02 ride up the inclined surfaces on the blocks 93 thus elevatingthe ink pad 90 into engagement with the marking edges 54 and 55.

In operating the machine, the marking edges 54 and 55 are inked bymoving the ink pad 90 in two directions normal to each other, themovement in one direction being horizontal to interpose the ink padbetween the work support and the combined ink-marking and perforatingdie, and the movement in the other direction being vertical to bring theink pad into engagement with the marking edges 54 and 55. After the inkpad 90 has been returned to its normal position disaligned from the worksupport, the operative locates the work on the plate 61 against thegauge I0 if no paper is used or on the paper I3 against the gauge I4when paper is used.

After the work has been gauged the operative steps on the treadle 32 andbrings the die down toward the work the stop 35 limiting this movementwhen the marking edges 54 and 55 are spaced about A" above the work.This small spacing insures the retention in the machine of the safetyfeature inherent in Model R machines while preventing blurring of thework which might occur should the marking edges 54 and 55 engage thework during the preliminary downward movement of the die. The operativethen steps on the treadle I8 to throw in the power mechanism for movingthe die downwardly to perform the combined ink-marking and perforatingoperation.

In some cases it may be desirable to move the marking edges 54 and 55downwardly through the treadle 32 into engagement with the ink pad afterit has been interposed between the die and the work support.

l. A combined ink-marking and perforating machine having, incombination, a marking die, a work support, means for relativelyoperating the die and the work support to mark the work, a carriageinterposable manually between the marking die and the work support, andmeans carried by the carriage and movable vertically automaticallythereon in a direction away from the work support and towards themarking die for: depositing marking material thereon.
